Digital BW, The Print

John,

I think this is a very good case of where it is worth reading Livick's 
results rather than Wilhelm's.

Here's a short quote from a piece I wrote about him: "his coating of 
choice is Clearshield Original although some may prefer the thinner 
Clearshield LL. Although he found the widely available Lascaux's 
'Fixativ' to provide little benefit on its own, it both reduces the 
drying time needed before coating with Clearshield and gives some 
additional protection."

And yes, it does appear to give very considerable protection from his 
tests. Of course you many not want your prints to last 300 years. I 
certainly can't be bothered with it.

Regards,

Peter Marshall
